GreenPalm is a certificate trading programme which is designed to tackle the environmental and social problems created by the production of palm oil. Exclusively endorsed by the Roundtable on Sustainable Palm Oil (RSPO), the GreenPalm programme is based on the principle that the best way to encourage people to work in a sustainable and responsible way is to reward them for doing so.By making or selling products which are covered by the GreenPalm programme food manufacturers and retailers can reward palm producers for working in a sustainable and responsible way, and tell their customers that they have done so. By selling certificates through the GreenPalm programme palm oil producers can earn more for their crop.
